KINGDRILLING DTH button bit description:

KINGDRILLING hammer bits are used with Down-the-hole hammers for drilling holes through a wide range of rocks types. In conjunction with DTH hammers, drill hammer bits are designed with a spline drive for rotating the bit in the ground. Drill bits are available in different sizes and different styles so they can drill a wide range of hole sizes. Our variety of Down the Hole (DTH) bits is manufactured using high quality materials to provide you with a fine balance between penetration capability and bit life.

FAQ:

1. What is button bit?

Button bits, or roller cones, have rotating cones that contain tungsten carbide inserts. Tricone, or three cone bits, are the most common; however, manufacturers continue to make two cone and one cone bits.

2. How do you drill through boulders?

Apply moderate pressure to the drill, and drill for one minute. Don't force the bit into the boulder; let the drill do the work. Remove the bit from the hole, and cool it in the pitcher of water. Lightly spray the boulder with water to remove dust and to cool the rock.

3. How about the common packing?

A: If there is no special packing demand, we will take it as our normal packing. First in small carton, and then put in the bigger carton together to make sure goods completed.

4. How to check the product are the exact one you want?

A: If possible, please attach one reference picture to avoid any misunderstanding or any links from our website for a better understanding.

Domed/Round Buttons are usually used as gauge buttons of DTH Bits, suitable for very abrasive and very hard formations.

B. Semi-ballistic Buttons
Semi-ballistic Buttons are usually used as gauge buttons and front buttons of DTH Bits, suitable for medium abrasive and hard formations.

C. Ballistic Button
